Application filed October 25, 1923. Serial No. 870,804.

strand material cramped the turns of matea '10 rial already on the drum/down the inclined face thereof, or to provide a drum with a 'flatperiphery and an element for {pushing across the face thereof the turns strand material wra ped thereon. Both of these forms 'of fee ing devices depend for their action upon a cramping of the turns of strand material, which in many instances damages it. To avoid this squeezing and consequent damaging of the strand material grooved capstans have been provided, the

grooves separating the strand material, but 1n order to secure a feeding of the strand material thereacross it was necessary to provide a pair of such drums around both of which the strand material was looped back and forth. This construction is expensive and results in a bending and straightening of the strand material a multiple number of times, which in some instances is very ob- 3o jectionable, such as the reeling of electrical conductors made of copper where a repeated bending and straightening thereof is detrimental to its tensile strength. In addition the'two drum arrangement occupies considerable floor space.

An object of this invention is to provide a feeding device comprising a drum or cap stan adapted to receive a plurality of adjacent turns of strand material and s0 designed that all the friction and cramping incident to the side slip of strand material during its passage across the drum is avoided.

Another object of the invention is to provide a drum or capstan adapted to receive a plurality of adjacent turns of strand material with means for positively feeding the coils of strand material across the drum. Other objects and advantages of the present invention will more fully appear from the following description and will be particularly pointed out in the appended claims.

In the accompanying drawings,

' in elevation,

Fig. 1 is a vertical sectional view, partly of' a feeding device or capstan made in accordance with the invention;

Fig. 2 is an elevation thereof partly in section Fig. 3 is an enlarged fragmentary vertical sectional "iew taken on the lines 33 of Fig.2;

Fig. 4 is an enlarged fragmentary horizontal sectional view of one of the endless members, and

Fig. 5 is an enlarged ,fragmentary side elevation thereof.

Referring now to the drawings in detail in which like reference numerals designate simllar parts throughout the several views, 10 and 11 indicate oppositely faced cupshaped members w ich comprise the ends of -a feeding device or capstan made in accordance with the invention, these ends being held in spaced relationship by means of an.

annular ring 12 which has its edges grooved as indicated at '13 (Fig. 3) to rest upon flanges formed on the cup-shaped members, the ring being securely positioned by means of screws 14: or other suitable means. The joint between the cup-shaped members 10 and 11 and the annular ring 12 is, as shown, of such. character, that theouter surface of the cup-shaped members and the annular ring 12 are flush. The corners of the-cupshaped members 10 and 11 are rounded as shown in Fig. 3, the purpose of which will hereinafter appear.

The end members 10 and 11 and annular ring 12 constitute a drum and thesaid end members are provided with bosses 15 and 16 (Fig. 1) to provide hearings to receive a non-rotatable shaft 17 upon which the drum is free to rotate,'being held in longitudinal position on the shaft by. means of collars ,l8and 19 pinned to the shaft.

. Encircling the periphery of the drum are a plurality of belts 20 which are rotatabl mounted upon idler pulleys 21. These pu leys are rotatably mounted upon stud shafts 22 secured in parallel ears 23 integral with the-cup-shaped member 10 and adjacent the corner thereof. The endless belts 20 also pass around pulleys 24 which are fixed to stud shafts 25 rotatably mounted within suitable bearings formed in ears 26 integral with the cup-shaped member 11 and adjacent the cbrner thereof. Also fast upon the stud shafts 25 are spiral gears 27 which mesh with worms 28 mounted upon the outer ends of radially disposed shafts 29 which have on their inner ends bevel gears 30 which mesh with a bevel gear 31 pinned to the shaft 17.

, The bolts 20 are disposed about the periphcom risin a cable 40 are 20, it may larly ery of the annular member 12 disposed in shallow grooves made in said annular member, as shown'in Figs. 1, 2 and 5, and the shafts 29 are arranged radially like the spokes in a wheel and have bearings formed in projections 33 and 34 made integral with the outer face of the cup-shapedmember 11. as shown in, Figs. 1 and 3.

The drum is driven by means of a worm wheel 35 secured to the boss 15 (Fig. 1) which meshes with a worm 36 connected with any suitable source of power (not shown).

In the operation of the pulling device or capstan a number of turns of strand material, which is shown in the drawings as wra ped about the drum and in contact with t e belts 20. Each of the belts .is provided with a plurality of projections 37 which are so positioned that the projections of all the belts are in spiral alignment around the peripheryv of the drum and when the turns of strand material are wrapped around the periphery of the drum, they lie in contact w1th the projections 37, as shown in Fig. 1. As the drum is rotated, throu h the medium of the worm 36 and worm wieel 35, the bevel gears 30 are rotated around the bevel gear 31 which is fixed to the non-rotatable shaft 17 The rotation of bevel gears 30 through the shafts 29 and worms 28 drive the bevel gears 27. These gears cause a rotation of pulleys 24 which serve to feed the belts 20 across the periphery of the drum, the projections 37 carried-by the said belts, engaging the turns of strand material on the drum and feedin the periphery of the drum. The projections 37 are so arranged that the-turns of strand material are out of contact with each other whereby all cramping and friction on the strand material is obviated.

Where the improved pulley device or capstan is subjected to heavy loads, which might tend to cause the slipping of the belts be found desirable to employ chains in place of the belts shown and sprockets in place of the idlers 21 and 24;.

Although the capstan shown is particuadapted for the reeling of electrical conductors or cables, it is not limited to this use and may be adapted for a variety of other purposes and the invention is only to be limited by the spirit andx scope of the appended claims.
